colourless ostiole. Rhizoidal hyphie abundant. Lateral

 terminal hairs spreading, branched, very stiff, the cell walls 

 thick, incrusted, brown. Asci large, clavate, stalked, up to 

 loo/'. X I.V20/V. 8-spored ; spores ellipsoid (side view fusiform)

DiSCOMYCETES. 



DiscocERA gen. nov. 



Ascomata parasitica, sessilia, immarglnata, colorata, firme 

 ceracea ; disco patelfeto, dein plano-convexo. Asci clavati, 

 supra rotundati, inoperculati, 8-spori ; paraphyses tenerae, 

 supra ramosissimae, epilhecium densum formantes ; Sporae 

 ellipsoideae, continuae, hyalinae. 



A somewhat remarkable genus resembling Humaria in 

 the appearance of the large smooth spores, but the inoper- 

 culate asci and the branching of the paraphyses to form a 

 dense epithecium show its affinity with the lichenicolous 

 genus Xcsolcchia. 



D. LICHEXICOLA n. Sp. 



Ascomatibus.subrotundatis, usque ad 1.5 mm. latis, fusco- 

 coccineis, glabris. Ascis elongato-clavatis c. 140/y. x 20/7., 

 membranis ad apices c. up. crassis, cum iodo vino-rubescen- 

 tibus ; paraphysibus tenerrimis, c- i// crassis, septatis, supra 

 persaepe ramosis, interdum irregulariter nodosis, hyalinis, 

 granulosis, ad basim coalitis; sporis glabris, intus roseo- 

 hyalinis, guttulatis 20-26/v. x 10-13/7.. 



Ad thallum Lichenis, supra saxa. Coll. W. Watson at 

 Treborough, Somerset, Dec. 191 5. 



The fungus is a dark crimson-red when drv, but when 

 moistened becomes lighter in colour, and, under the micro- 

 scope, the whole ascus contents, more especiall}' the spore 

 guttulae, are a beautiful rose-red.
